Study On The Integration Characteristics Of An Integrated Solar Combined Cycle (ISCC) System

In recent years, China has become the largest carbon emissions country, combusting a large number of fossil fuels, not only facing the international emission reduction pressure, but also the pollution of the environment has a negative impact on the people health and production. The development of renewable energy power generation, balancing energy consumption structure, is always a national policy. With the investment of resources in research institutes and companies, the solar thermal power generation will become a new way of generation. Because of the thermal storage technology is immature and the initial construction cost is high, the traditional solar thermal power generation, compared with conventional power generation, has no commercial competitive advantage.This paper, based on the combined cycle system which has 9FA gas turbine and heat recovery steam generation, uses commercial software Aspen Plus to study the integrated solar energy potential of the basic combined cycle system in the different integrations. Using the data of the largest integrated solar capacity to guide the thermal complementary integration and study the thermal performance of solar thermal utilization for the next step.Mathematical modeling of Cavity Receiver is set up, and using the commercial software TRNSYS to simulate the tower concentrating solar technology which integrated with combined cycle system. From the first law of thermodynamics and the second law of thermodynamics, the thermodynamic properties of different integrations are analyzed, which can be taken reference for engineering.The low-cost trough concentrating collector technology integrated with combined cycle system, the conduction oil is the integrated medium, which has some operation problems. This paper presents a novel integrated solar combined cycle system, which the compressed air from gas turbine is the integrated medium, through the thermodynamic studies and economic analysis, this novel system, compared with traditional integration, has significant thermodynamic advantages and economic advantages.
